Toallwhomz'ffmag/ concern: l

Be it known that I, JOHN JWHITAORE, a` citizen of the UnitedStates, and a resi-` dent of Canton, in the county of Stark and State of Ohio, have invented certa-in new `and useful improvements in `Building-` Bricks, of whichthe following is a specification. i Y j The invention relates to ribbed bricks' for building walls with air channel@A andthe Obj ect -of the improvement is to make abrick with ribs or projections on 'oneside only of -a bedor body plate, whichmay Ybeflaid in a wallV with interlocking joints of mortar.

A further object of the invention is toV make a'wall with a plurality ofV continuous longitudinal air' channels in each course of bricks, and tov separate the beds for the mortarjoints fOrl preventing the formation ofV a -continuous layer of mortar from the outer to the inner portions of the wall.

The objects of the invention thus set forth in general terms, are attained bymaking and marketing the brick in the formV of a hollow block having side and partition wallslongi-,j` tudinally weakened along the median 'line for ready separation at the place of use intoA 'bricks having bed orvbody plates with up# standing ribs forming lair channels along each side and in the median portion of each brick; and by providing an upstanding T-rib of brick material in each side channel partially closing the opening thereof and forming a bearing for a mortar joint, with the usual longitudinal grooves inthe bottom of the brick for interlocking with' the mortar of the joint.

A preferred embodiment of the invention thus generally described, is illustrated in the accompanying drawing forming part hereof, in which- Figure l is an end view showing a hollow block cut for'breaking into bricks;

Fig. 2, an end section of an eight inch wall made with the improved bricks;

Fig. 3, a section of a twelve inch wall eme' borlving the present invention; Fig. 4, a perspective view of a brick for making an eight inch wall; and

Fig. 5, a perspective view showing a method of building a wall with the ribbed bricks and ordinary corner bricks.

Similar numerals referto similar parts throughout the drawings.

As shown in Fig. 4E, each brick for an eight'inoh'wall is `'made of a bed'or body` in width continuously plate` l extending from' the inner to the Outer faces 2 and 2a formed bythe-inner and outer `upstanding ribs 3 `and 3a of the brick, are spacedv the upstanding partition ribs Bb, forming an airchannel 4 along each sideof the brick, and a lo Inr each side airchannel is provided Aa longitudinal upstanding T-rib 6 intermedi'-V ate the face and partition ribs and preferd ably made slightly shorter than the same;

downward into the air channel, and at the same time forms a bearing for a mortar joint for which a lateralbearing is formed by the ends of the adjacent ribs.

The bottom and innerface of the bricks are provided with` the usual longitudinal grooves 7 and 7a or plaster'used in building a wall, which grooves may be dove-tailed in the usual manner;4 and the `outer face 2a of each brick is preferably made about eight inches long with a depth of two and three-eights inches so-tliat thebrickmay be laid flatwise ina wall and' sponding to ordinary standard brick with which it may be combined in the construction of a wall.

The bricks are also preferably made either eight inches or'twelve inches, or some other multiple of four inches in width, so as to form an eight inch wall as shown in Fig. 2 or a twelve inch wall as shown in Fig. 3; in which latter event, an additional pair of partition ribs k3b with an intervening T-rib 6 may be provided along the median line of the brick, so as to increase the strength of the wall and provide an additional mortar joint along the middle thereof.

In the construction of a wall, the bricks are laid with their bed or body plate downward, andV mortar is applied to the tops of the upstanding ribs without, however, dropping down to any extent past the head of the T- rib; which prevents the side channels from being filled with mortar.

A sufficient amount of mortar is used to form a suitable layer on the tops of the ribs and to enter the longitudinal grooves 7 in Patented Dec. 2, 1919..

within which ribsngitudinal air channel `5 .1n the median portion thereof.

mortar for. engaging the mortar will present a face corre` Tlie'mortar joints 8 are limited in Width tothe tops of the ribs forming the side air channels l, and do not lextend across the air channel 5; and it is evident that any Water or moisture which may run or seep along the Ymortar joint from the outer face of the Wall, will be trapped, first in the air Channel on the outer side of the T-rib and neXt in the air channel on the inner side of the T-rib, before such water or moisture can reach the air channel 5 in the median portion ofthe brick; and it is also evident that no Water or moisture can pass beyond the air channel 5 so as to affect the inner portions of the Wall, and'much less the inner Y face formed by the inner brick.

IV claim: y Y Y 1. A, brick comprising a continuous bed or body platehaving upstanding` side `and partition ribs forming air channels alongV each side and in the median portion of the. brick, with an upright T-rib in each sidev channel partially closing the opening thereof. r

body plate having upstanding side and partition ribs` forming air channels along each side and inthe median portion of the brick, with .an upright T-rib in each side channel Ipartially, closing the opening thereof, the T-rib 'being slightly shorter than the side and partition ribs. Y

3.1i brick comprising a continuous bed or body plate having upstanding side and artition ribs forming' air channels along i each side and in the median Vportion of the brick, with an upright T-rib in each side channel partially closing the opening thereof,there being longitudinal grooves in the bottom face of the/brick opposite the side channels therein. Y

j 4. Hollow Wall construction comprising superposed bricks each having a bed or body plate extending theV full Width Vof the Wall,

with upstanding side and partition ribsV forming air channels along each side and in the middle portion of the Wall, and an upstanding T-rib in each side channel partially closing the opening thereof, With mortar jointsbetween the ribs of one brick and the bottomof a superposed brick.

5. Hollow LWall construction comprising superposed bricks each having a bed or body plate extending the full Width of the Wall, With upstanding side and partitiongribs forming airV channels along eachside and inV the middle' portion `of the WalhfandV an up- A standingT-rib in each side `channel slightly shorter than the adj acent' ribs and partially closing the openingof the channel, with mortar joints between' the ribs of one brick and the bottom of a superposedbrick.

6. Hollow Wall construction comprising lsuperposed bricks each having a bed or bodyY v l Y i plate extending the Afull Width of the Wall, 2. A brick comprising a' continuous bed or closing the opening thereof, there being longitudinalfgrooves in thebottom face opposite the side channels, and a mortar joint j laid on the tops of theribs and entering the grooves to interlock the bricks.
